High in the cloud forests of Peru is the mountaintop fortress of a lost civilization and an ancient legend of murder. The Chachapoya, or Cloud Warriors who lived over 400 years ago, vanished virtually overnight. For years, anthropologists have been hunting for who or what killed these people. Now, the discovery of a site with more than 80 corpses could solve this mystery. National Geographic joins a team of archaeologists and anthropologists who believe the answer is hidden in the bonestesting theories from an Inca massacre or an epidemic brought by the Spaniards to a ritual sacrifice or assassination by a rival tribe to finally close the case on this lost capital's ultimate collapse.

For the first time ever, National Geographic presents its programming in DVD-R format. Available exclusively through this site, you can now own more of our award-winning specials and documentaries in a high-quality DVD format.

How our DVDs and DVD-Rs Differ

Customers who purchase programs in the NG DVD Exclusives Library will receive a non-interactive, play only disc. There is no chaptering information on these DVDs, but there are chapter marks approximately every five minutes, which make it easy to fast forward through a program. The DVD-R format provides the digital video and audio quality you expect from all of our DVDs.

NOTE: The NG DVD Exclusives titles are not closed-captioned. We apologize for any inconvenience this limitation may cause.
